What is the electron configuration for helium? - Socratic
Jun 26, 2016 · 1 Answer. Helium, #"He"#, has an atomic number equal to #2#, which means that it has #2# protons in its nucleus. A neutral helium atom will thus have #2# electrons surrounding its nucleus. This means that the electron configuration for helium has to account for only #2# electrons. Both of these electrons are located on the first energy level ...
How do you write the noble-gas electron configuration for helium ...
Jan 8, 2018 · 1 Answer. Just as simple as [H e]! Helium's electron configuration is [1s2]. But, helium is in the last row of the periodic table, which are noble gases. So, helium's noble gas configuration will be. [H e]. Just as simple as [He]! Helium's electron configuration is [1s^2].
What is helium's electron configuration? - Socratic
Oct 26, 2016 · 1s^2 Helium has an atomic number of two which means it has 2 protons. A neutral He atom will also have 2 electrons. Here is a review of determining the number of subatomic particles in an atom. In its ground state, helium will have two electrons in the first energy level. These electrons are found in the 1s sublevel. Here is a video which discusses how to write …
1s^1 2s^1 is an electron configuration of an excited atom
Jun 29, 2017 · Helium. For starters, your atom contains 2 electrons, so right from the start, you should be able to say that you're dealing with a helium atom, "He". You can say that because a neutral atom has equal numbers of protons inside the nucleus and of electrons surrounding the nucleus, regardless if the atom is in its ground state or not--keep in mind that this is true when …

Electron Configuration - Chemistry - Socratic
Electron Configurations are an organized means of documenting the placement of electrons based upon the energy levels and orbitals groupings of the periodic table. The electron configuration for the first 10 elements. H 1s1. He 1s2. Li 1s22s1. Be 1s22s2. B 1s22s22p1.
What is the electron configuration for helium (He)? A. 1s1
Sep 29, 2020 · The electronic configuration of helium atom with atomic number 2 can be written as, 1s². The s orbital can accommodate only two electrons in them and helium having only two electrons gets completely filled. Helium being the inert gas has the most stable configuration. Therefore, 1s² is the electronic configuration of He.
Noble Gas Shorthand - Chemistry - Socratic
A Noble Gas is a group of elements that in their standard state have a filled electron cloud. These elements are found in the 18th column of the periodic table and include Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe) and Radon (Rn). They are all odourless and colourless mono-atomic elements. Because these elements are already ...
